Securely mount your smartphone with the Mobile Phone Clamp with Pocket Stand from Really Right Stuff. This mount fits devices 2.3 to 3.4' wide and has two 1/4'-20 standard threaded holes for mounting on tripods, monopods, and more. The mount adjusts using a knob and a custom hex key secured within the clamp with a pair of rare earth magnets, while a knob locks the phone in place. Angled, rubber-lined jaws hold your device in place. The included Pocket Stand folds down with a click and attaches to the back of your clamp with a ball joint and its own tightening knob. The stand has a 1/4'-20 threaded hole for tripod mounting.
